Super Download Uses Mobile Data + WiFi for Faster Internet Speed

Whenever a download occurs on an Android device, the devices either uses its mobile data or WiFi connections to get the job done. Unfortunately, however, most devices use only one connection to download a single file. Recently, an application was released that allows users to take advantage of all connected networks in order to download a file. Aside from being really cool, it also means faster downloads.
The application is aptly named Super Download. Developed by XDA Recognized Developer elban, it allows users, as mentioned, to use any network to download files. As elban explains:

Download web files much faster by using wifi and mobile data at the same time!
Share or open a link from any program, like the web browser, and download it at speeds up to two times faster than usual.
This is the only tool that can download using wifi and mobile data connection simultaneously!

Being on a WiFi connection means getting whatever speeds you get on your WiFi connection. Add that to the 3G or 4G speed, and all of a sudden, the Internet on your device is even faster. It is also simple to use, as users just install the app and enable what they want in the menus. Of course, root is required.
